Anterior disc position has been highly correlated with temporomandibular disorders (TMD). It was hypothesized that internal derangement of the temporomandibular joint may be a part of a joint phenotype that imparts an increased risk for joint disorders. If this hypothesis is true, an increased prevalence of joint disorders in individuals diagnosed with displaced discs should be expected. A total of 263 symptomatic TMD patients and 82 asymptomatic volunteers was examined. Asymptomatic volunteers with anteriorly displaced discs were twice as likely as asymptomatic volunteers without disc displacements to report pain/dysfunction in other joints. Symptomatic patients with and without displaced discs reported an increase in other joint problems three to four times greater than in asymptomatic subjects. Compared to symptomatic TMD patients without disc displacement, symptomatic TMD patients with anteriorly displaced discs were also twice as likely to report other family members as being affected by TMD. Familial aggregation of TMD and an increased prevalence of other joint problems in these individuals may represent more than a serendipitous occurrence.
关节盘前移位与颞下颌关节紊乱病（TMD）高度相关。有假说认为，颞下颌关节内紊乱可能是关节表型的一部分，会增加关节疾病的风险。如果这一假说成立，那么预计在诊断为关节盘移位的个体中，关节疾病的患病率会升高。总共检查了263名有症状的TMD患者和82名无症状志愿者。有前移位关节盘的无症状志愿者报告其他关节疼痛/功能障碍的可能性是没有关节盘移位的无症状志愿者的两倍。有和没有关节盘移位的有症状患者报告的其他关节问题增加幅度比无症状受试者大三到四倍。与没有关节盘移位的有症状TMD患者相比，有前移位关节盘的有症状TMD患者报告其他家庭成员受TMD影响的可能性也高出一倍。TMD的家族聚集性以及这些个体中其他关节问题患病率的升高可能并非偶然。
